Re: ssmith1952: AC inverter shuts solar system down
Watts is a rate--Like Gallons per Hour Watt*Hours is an amount--Like Gallons total So, if you have a 100 AH @ 12 volt battery, its storage capacity is: 100 AH * 12 volts ~ 1,200 Watt*Hours Your cell …1 · -

Re: 12v dc vs 220v ac usage from PV
In the old days, AC appliances where pretty wasteful of energy. I have a (very nice for me) 30 year old stereo radio/tape player that takes 20 Watts off and 40 Watts just turned on (no music playing)…1 · -
Re: Inveter backup with 100ah battery
The 85% (typically 80-90+%) inverter efficiency only applies to a "moderately to heavily" loaded AC inverter output. When you very lightly load a large AC inverter the efficiency is much le…1 · -
Re: Inveter backup with 100ah battery
Very roughly: 250 Watt load * 1/0.85 inverter eff * 1/12 volt nominal = 24.5 Amp load @ 12 volts You have a 12 volt @ 100 AH battery, to take the battery dead: 100 AH / 24.5 amps = 4.1 hours to "…1 ·
